Projectile Motion Calculator
Projectile Motion Calculator is a browser-based calculator tool on CalcToolsBase. Free, browser-based Projectile Motion Calculator with instant, clearly-labelled results. No signup, no uploads. To use it, enter your values and view the result directly in your browser — no signup and nothing to install.
Use Projectile Motion Calculator to work out projectile motion: give it your initial velocity and launch angle, press Calculate, and read off the range, height and flight time — all worked out on your device.
About this calculator
With the Projectile Motion Calculator you can work out projectile motion in a few seconds. Supply your initial velocity and launch angle and read the range, height and flight time, computed via the range and maximum-height equations. The tool is free, runs locally, and keeps every value on your machine.
Made for physics students, it gives the range, height and flight time from your initial velocity and launch angle in one step — clearly laid out, free to use, and computed entirely on your device.
How to use
- Enter the initial launch speed.
- Enter the launch angle in degrees.
- Press Calculate to find the trajectory.
- Read the range, maximum height, and flight time.

Technical notes
Projectile Motion Calculator uses the projectile-motion equations — range = v²·sin(2θ)/g and maximum height = v²·sin²θ/(2g) — from the launch speed and angle.
Results assume ideal conditions and consistent units, so convert your inputs to the units shown before calculating.
Results are rounded for display; the underlying calculation keeps full precision.
FAQ
What assumptions are used?
It assumes no air resistance, level ground (launch and landing at the same height), and gravity of 9.81 m/s².
What launch angle gives the greatest range?
On level ground, 45 degrees gives the maximum range for a given speed.
What units does the projectile calculation use?
Speed in metres per second and angle in degrees give range and height in metres and time in seconds.
Does the Projectile Motion Calculator send my data to a server?
No. The Projectile Motion Calculator runs entirely in your browser, so nothing you enter is uploaded, stored, or shared.
Worked example
Launched at 20 m/s and 45°, range = v²sin(2θ)/g = 400 × 1 ÷ 9.8 = 40.8 m.
